When handing you the contract on Ennodius’ head, Nazir will provide a few facts about the target: "He lives just outside Anga's Mill, in the woods. He was once the miller. Now Papius is just a paranoid recluse who thinks someone is out to get him. And he's right." When you arrive at Anga’s Mill, you may overhear a conversation between Ennodius’ old colleagues, Kodrir and Leifur:

Leifur: "Whatever happened to Ennodius? He just up and left."Kodrir: "Don't know why you're asking me. But I'm glad that damn Imperial is gone. Something wrong about him."Leifur: "You're all heart, Kodrir. I bet Lady Mara is weeping a special tear for you right now."

When you approach the paranoid Imperial at his camp, he will be quite anxious, asking: "Why are you here? Get away from me!"
Three options will be available:

Topic

Dialogue

"You were right to be paranoid, Ennodius."

"What? What do you mean? Oh! Oh... no... No!"

"Die, worm!"

"Aiiiiiiiieeeeee!"

(Remain silent)

"Who are you? You... you're with the Dark Brotherhood, ain'tcha? I knew it. I knew you'd come for me!"

All three options will make him flee with the words: "By the gods! Somebody help me!" When the deed is done, a return to Nazir will make him ask: "How went your meeting with Ennodius Papius? Did you prove his paranoia legitimate?" When you tell him that Ennodius is no more, he will jokingly say: "Good. And I hope you were careful in that lumber mill. Those splinters and rusty nails can be quite nasty."

Ennodius was supposed to be able to tell you a bit about himself if you met him outside the related quest. However, since he only spawns during the quest, this dialogue will never be heard: "I used to work at Anga's Mill, but I... I had to leave.", "Someone's after me I tell you. They're watching me. Somewhere." and "Don't talk to me. You could be one of them."

Under the waterfall that is just upstream from Ennodius' camp, there is a small amount of loot: a barrel and a strongbox. On the stream bed three yards or so downstream from the strongbox, under the water, there is a quicksilver ingot that is very difficult to notice unless you pass directly over it.
